8 pm Community (NBC) | After getting shut out of “The History of Ice Cream,” the study group begins its European History class with Prof. Noel Cornwallis (played by Malcolm McDowell, Entourage) — which of course winds up with the gals dressed as Bavarian milkmaids and reintroduces Jeff and Shirley’s German foosball foes. Oh, and Chang’s back!
